Aerodynamics is the study of how gasses interact with moving objects. We offer body parts such as front splitters, rear wings, side skirts, rear diffusers, exterior M style mirror caps for BMW cars in carbon or high-gloss black painted.
Air obviously isn’t as dense as liquid, but it’s still touching stuff. So, there is friction when something moves through it and makes drag probably the most important aerodynamic factor that we have to consider.
